🌊 🌊 New Paper Out! 🌊 🌊

Led by Chris Brierley, our manuscript on Indian Ocean variability across the latest edition of various paleoclimate modeling intercomparison projects () is out in Climate of the Past (): cp.copernicus.org/articles/19/

We look at the consistency (& lack thereof) of simulated temperature responses & impacts on interannual hydroclimate changes over the Indian Ocean rim for the , , last , and an abrupt 4 x CO₂ simulation.

Nerdy details: we show using of (δ¹³C) and (δ¹⁸O) that **ONLY** Miliolida benthic foraminifera (including , , & - pictures attached) found **ONLY** in sediments proximal to methane hydrates (site U1446 is in the NW Bay of Bengal) contain wildly negative δ¹³C signatures characteristics associated with methane dynamics in marine sediments. Check out those δ¹³C values!!

🚨🚨New Paper Alert🚨🚨

We have a new paper out in Earth & Planetary Science Letters () entitled “Indian margin methane hydrate dissociation recorded in the carbon isotopes of benthic (Miliolida) foraminifera”

Main take home message: we have identified a group of (unicellular organisms living at the bottom of the ) whose shell chemistry carries signatures of dynamics within .

New paper out by @willerstorfi et al. in documenting the evaluation of planktic foraminiferal Na/Ca as a proxy for ocean salinity using plankton tows, sediment traps, and core tops: sciencedirect.com/science/arti?

Take home message: looks like this proxy can be quite complex due to varying Na-bearing phases of the foraminiferal calcite, even though the Na/Ca in some of these phases may be strongly correlated to salinity. The authors conclude instead that due to the effect of [CO₃²⁻], foraminiferal Na/Ca over Cenzoic timescales may be a better proxy for major ion chemistry than salinity changes in the ocean.

Chalk another one up for the ever-charismatic universa - this time as 's classic, From Mars to Sirius.
